Statistical assessment of background levels for metal contamination from a subtropical estuarine system in the SW Atlantic (Paranaguá Estuarine System, Brazil)

Trace metal contamination and benthic assemblages in Subaé estuarine system, Brazil.

Evaluation of Mercury Contamination in Sediments from Santos - São Vicente Estuarine System, São Paulo State, Brazil

A distribuição da contaminação por mercúrio no sistema estuarino de Santos São Vicente foi observada pela análise de 31 amostras de sedimentos coletadas desse sistema, incluindo as áreas de manguezais localizadas em zonas sob influência urbana, industrial e portuária. Os valores obtidos de Hg variaram de 0,04 a 1,19 μg g , sendo que cerca de 90% das amostras apresentaram concentrações superiore...

Ecotoxicological Assessment of Sediments from the Santos and São Vicente Estuarine System – Brazil

Sediments represent an important repository of pollutants and a source of contamination for the aquatic food web. Toxicity tests using amphipods as test-organisms have been employed in the assessment of marine and estuarine sediments, together with chemical analyses. The present work aimed to evaluate the quality of sediments from six stations situated in the Santos and São Vicente Estuarine an...

toxic metal distribution in the core sediment of cochin estuarine system (ces)

this article present the result from a study of two sediment cores collected from theenvironmentally distinct zones of ces. accumulation status of five toxic metals: cadmium (cd), chromium(cr), cobalt (co), copper (cu) and lead (pb) were analyzed. besides texture and chns were determined tounderstand the composition of the sediment. enrichment factor (ef) and anthropogenic factor (af) wereused ...

Biomonitoring of metal contamination in estuarine ecosystem using seagrass

Metals concentrations (As, Cd, Cu, Hg and Pb) in seawater, sediment and the seagrass (Enhalus acoroides) were analysed at Pulai River estuary, Johor Straits, Malaysia. In this research, Enhalus acoroides was used in order to find it's efficiency in up taking metals with a role in phytoremediation. Seawater, sediment and Enhalus acoroides samples were collected, and data of Pearson's correlation...
